Check this for mass user creation using SCAT
You can, use tcode SCAT.
First, make sure your client setting (SCC4) is enabled with ' X eCATT and CATT allowed'. Just in case your
Production disabled this.
Then, you need to create a simulation (test case) of creating new user id by calling tcode SU01 later.
Test case must start with Z, example ZCREATE_NEW_USER. Create this case, put title and choose component as BC (basis components).
Save and choose Local if you dont want to transport it or choose a dev. class (example ZDEV) if you want to transport it later.
Go back and click Change button. Then key -in Object as example SU01, and choose Record button on top. When it prompts to enter Transaction code, key in SU01 (if for roles, key-in PFCG) and begin recording. As usual in SU01 create 1 user id, dept field, password, roles, group and so on.
Make sure you press Enter on each field because we want to capture the value/object and SCAT is a bit stupid if you become familiar later....but still useful...indeed.
- You will see a clock on the bottom which means the recording process is on going. Once done, click Back button and press End button to end the recording.
Note - The profiles are all the same. Then this is much easier...no need to enter the roles/profiles, just duplicate this ID and change the name, dept and password only.
Okay..first stage has finished. Then double click the Object to begin
inserting parameters. Then you will see an object for each fields that
you run from SU01. Choose the right field example user id (BNAME) and
choose button 'Insert Import Parameter (F6)' and you may click Next
Screen to 'watch' what have been recorded and proceed to choose
several other objects like password field (PASSWORD1, PASSWORD2),
roles field (AGR_NAME), group field etc. If you happen to choose the
wrong object, then you can reset back (Edit -> Reset
Parameterization). You may see so many junk fields captured and this
is because SCAT records every steps/dialogs.
Once done, choose Back and save this case. Then you need to click
'Goto -> Variant -> Export' and save it. After that use Ms Excel to
open it and begin inserting all other user ids. Save and close.
Remember to close this file because SCAT will use it.
Then last one, get back to SCAT and click button execute, processing
mode chose Background, choose external file 'the one you created with
Excel' and execute. At this moment don't use tcode SU01 bcoz you may
interrupt the simulation. Wait for the logs. If you see reds then
error was
happening.
